Mean-State Entropy Hierarchies and Classical Communication through Quantum Convolutions

Chunhe Xiong, Sunho Kim, Qing-hua Zhang +2

Quantum convolution provides a discrete-variable analogue of classical convolution, with the mean state capturing the stabilizer structure preserved under repeated convolution. We…

Private Capacity of Quantum Channels Induced by Non-stabilizer Environmental States

Chunhe Xiong, Sunho Kim, Long Long +1

We investigate the private capacity of quantum channels using the recently proposed quantum convolution theory for discrete-variable quantum systems. We focus on the role of the ma…

On the Simulation Cost of Quantum Finite Automata

Zeyu Chen, Junde Wu

This paper identifies exact probabilistic simulation cost as the natural quantitative measure of quantum advantage for finite automata under strict cutpoints. It gives sharp simula…

Matrix encoding method in variational algorithm of calculating eigenvalues and generalized eigenvalues

Alexander I. Zenchuk, Junde Wu

We propose a variational method for constructing the eigenvalues and generalized eigenvalues for an arbitrary complex matrix. The quantum part of our algorithm is based…

The State Cost of Classical Simulation of One-Way General Quantum Finite Automata

Zeyu Chen, Junde Wu

Under strict cutpoints, probabilistic finite automata (PFAs) and one-way general quantum finite automata (1gQFAs) recognize the same stochastic languages, shifting the theoretical…

Quantum Defect Analysis and Target-Orbit-Directed Correction via the Purpose-Oriented Framework: Applications to Entanglement Repairability and Teleportation Activation

Sunho Kim, Chunhe Xiong, Junde Wu

Quantum resource theories quantify advantages but suffer from ambiguous free sets, limiting target-oriented missions. We improve upon this by introducing a purpose-oriented framewo…
